Thanks for the info, good to know.
But I still have no idea what you are talking about with the statement in bold because I have a built 340 in front of it rev' 7 and have a built 410 stroker as well that shifted great 6500+rpm in front of the same rig.
I run no return spring either with about 1 1/2 of free travel before disengagement.
I still wonder if guys just tightened up the free play some at the fork rod, if that would fix this.
I believe all you say but the text in bold, cause my setup disproves that.
So I guess i'm letting you know that it works awesome.
